Hi, I'm Ciarán

(It's pronounced KEER-awn)

I'm a Software Developer with over 8 years of experience, currently working at Alludium AI. I've mostly worked with React and Typescript. I have 2 cats and do bouldering and board games in my free time. I chill in Dublin, Ireland.

I'm looking for my next role to work on great projects and sound people. Reach out if you think you have something interesting.

Skills I know pretty well

• Typescript
• React
• Tanstack Query/Router/Start
• Next.js
• Node.js
• Playwright
• Vite/Vitest
• SQL
• Can still write a Webpack config if you REALLY need one

Skills I'm learning/tinkered with

• AI Agents
• Python
• Rust
• Convex

Previous Companies

• Apata
• Evervault
• Web Summit
• Singlepoint Solutions (now Version 1)

Intresting projects I've worked on

• "Oh s***, the conference has been cancelled because of the pandemic, we need to run a virtual live streaming site to tide us over"
• Took the UI of Evalite, an AI evals tool by Matt Pocock, and converted it from Remix to Tanstack Start
• XState is cool, but data fetching is better in Tanstack Query. Converted a whole data fetching layer from XState to Query.
• Spending too much time answering peoples questions on the Tanstack Discord
• Wrote a genetic algorithm in CUDA C++, back before the AI craze took over
• Small contributions to Query, tanstack.com, tRPC, etc. Even have a rust-lang pr completed as well.
